33 * \brief Utility class for summerizing the informations of a JPEG
34 * fragment of an "Encapsulated JPEG Compressed Image".
35 * This information is a mix of:
36 * - the fragment offset
37 * - the fragment length
39 * Each instance of this class (they can be as many instances for
40 * a given Document as they are JPEG fragments and they are
41 * collected in a \ref JPEGFragmentsInfo )
